DEVICE FOR MAKING ORNAMENTAL BRICKS. v

T at whom, it may concern! Be it'known that I, MILTON. N. GRANT, a citizen of the United States, residing at Golumbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Devices for Making Ornamental Bricks, of which the following is a specification.

This invention relatesto a device for making ornament-a1 brick, and has-for its Object the provisionof means which may be readily attached to brick-machines which are already in use, said means being adapted to roughen the faceand sides of'the'clay which forms the brick as said clay is forced from the machine. a

Further objects and advantagesof the invention will be set forth in the detailed description which now follows.,, i 1n the accompanying drawings, Figure 1 is a side elevation of abrick-machine having the roughening deviceapplied thereto. Fig.

2 is a front elevation of said machine with the clay-conveyer mechanism removed. Fig. 3 is a sectional perspective view of a portion of the clay mass which is forced from the machine Fig. 4 isaperspective view of abrick, one of the edges and one of the ends of which have been roughened. Fig. 5 is a transverse vertical section upon line a: a; of the brick Fig. 6 is a side elevation of a portion ofthe machine shown in Fi 1 and of the clay in devlce.

The brick-machine shown in Fig. 1 will first be described, after which the method of set fort This ,brick-machme comprises a body ortion '5 to which'a head 6 is secured by bo ts .7. The numeral 8" (see'FigJ2) des'-. 'lgnates the wallsof the channel 9; through" which a continuous mass of clay 1'0 is for'ced from thebodylpiortion 5. As this clay passes 8;Which constitute" the brick-forming, die, are integral with a-flange 14. This flangeis secured by bolts to, a flange 16 which is car *ried by; the head 6. :The clay mass 10 is forced in a continuous body from the ma- Specification of Letters Patent.

chine and upon the conveyer-belt 11. This mass in width equals the length of a brick,

While in height it is equal to the width of a brick. The belt 11 conveys it to a suitable cutting mechanism, (not shown,) which slices it into bricksof the proper size. 4

The structure so far described is all of the usual andwell-known construction, such as is now in use in many brick-maidng plants.

The devices for rou hening the brick,

which are illustrated ina igs 1- and 2, comrise a vertically-disposed wire 17 and a orizontally-dispos'ed wire 18. The ends of these Wires are secured to hooks 19, said hooks passing through the rectangular frame 20, which lies behind the flange 16. T he inner ends of these hooks are threaded, as at 21, for the reception'ofthumb-nuts 22, by virtue of which construction the wires may be placed under any desired tension. Blocks 1 'the wires a slight distance in advance of themouth of the die. These wires are so posi' 'tioned that as the mass of clay 10 is forced from the machine the wire 18 will engage the to of the mass of clay, while the Wire 17' l engage one side of the mass of clay, said wires servm surfaces which they are in contact. Afterthe mass of clay 10 has been a's 'sed throu h the cutting mechanism, whic cuts said'c ay up into bricks 24;,0116'0f the sides 25 and one of the ends 26 will present whenbaked a rou'ghenedappearance which much resembles the surface presented by crepe paper and which formsja highly-ornamental building-brisk.

. In the former the'device illustrated "6 the wires havebeen omitted and an .L- sha ed'metallic plate-27 has been secured to t e =die 8'," as at 28, a depndingportion 29 ofthis plate serving as a scraper to roughenthe upper surfaceofthe clay clot or mass, as will be readily understood.

It will of course ,beunderstood that wires may be placed on ail four sides of the die 8 to roughen both ends and both edges of the brick .mstead of'rou hening only one end and one edge thereof, 1f desired;

The means for tensioning the wires is important; The tighter the, wires are drawn the more effect they will havein roughening to catch up and reugh'e'n the pended claims.
